Pigment and Prenyllipid Contents of Uninfected, TTO-CrtB, and TTO-Nb SAMT1–Silenced Plants.

(A) Total carotenoid (CAR) and chlorophyll (CHL) contents.

(B) Total α-tocopherol (α-T), γ-tocopherol (γ-T), plastoquinone-9 (PQ9), and phylloquinone (K1) contents.

(C) Upper noninoculated leaves were detached and incubated with 5 mM 5-aminolevulinate (ALA) for 12 h in the dark before determination of MgProto IX and MgProto IX Me contents.

Total lipids were extracted from 3-week-old plants and subjected to chromatographic analysis. Values represent means ± sd from three independent analyses. FW, fresh weight.
